SEPARABLE. BUTTON.

ZYIPZZLII-E'CJAIION forming part of Letters Patent No. 324,852, dated August 1885.

Application filed June 2-3, 1885.

To (LZZ 2071/0727, it 17m concern:

Be it known that I, HENRY G. LATHROP, a citizen of the United States, residing at St. .lohnsville,in the county of Montgomery and State of New York, have invented certain new and useful Improvements in separable Buttons; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the an nexed drawings, making a part of this specification, and to the letters and figures of reference marked thereon.

Figure 1 of the drawings is an elevation of my improved separable button, showing the two sections thereof disconnected from each other, and Fig. 2 asectional view showing the two sections connected.

The present invention has relation to con tain new and useful improvements in separable buttons;and it consistsin the details ot'construction substantially as shown in the drawings and hereinafter described and claimed.

In the accompanying drawings, AB represent the two bu tton-plates having, respectively, the hollow or tubular shank O, and the post 1), the latter being of such size in its circumference to enter and fit the tubular shank.

Upon the inner side of the button,plate B is an annular sleeve, a, of such size to admit the end of the tubular shank 0 between it and the post D when the two sections are connected together, thus forming a meansof strengthening the joint between the shank and post when the two button-sections are conneeted and locked together. The post D is with a slot in the "tubular shank (No model.)

double- L shape in form,- consisting of the slots 0 d,communicating by transverse slots 6, the slot d being of greater length than the slot 0, and extending through the end of the tubular shank. WVithin the tubular shank G is seated a spiral spring, f, or if preferred a rubber spring may be used, the object thereof being to retain the key I) in engagement with the slot 0, the spring pressing against the end of the post- D.

When it is desired to detach the two button-sections, the plate B is pressed inwardly until the key I) is on line with the slot 6, after which the plate is turned until the key is on line with the slot d, when the two sections may be separated.

Having now fully described my invention, what I claim as new, and desire to secure by Letters Patent, is

In aseparable button, the combination of the two buttonsections thereof, one of which has a hollow shank, a spring contained therein,and a loek-slot,and the other having a post with a key or feather formed thereon, and a sleeve surrounding the base of the post the required distance therefrom to form a space between it and the post for the end of the hollow shank-to enter when the two button-sections are connected together, substantially as and for the purpose set forth.

In testimony that I claim the above, I have hereunto subscribed my name in the presence of two witnesses.

HENRY GROS LA'll-IROP.
